I use a number of different things. Sometimes I mix it with the foundation, sometimes I apply it only in certain areas and sometimes I do both. It really depends on how I feel, the texture and skin color of the model and what the job calls for.
1. Stila's Illuminating Tinted Moisturizer
I love that you can use this product alone or mixed with foundation. Perfect for summer since it's lightweight.
2. Revlon Skinlights
Note: This product is discontinued and I stocked up on like a million of them before they were gone. I believe you can still purchase them on Ebay.
3. Make Up For Ever
Has beautiful speckles of gold in it which makes for a beautiful highlight on women of color.
Note: This product has also been discontinued. Again, Ebay is your friend!
5. NARS Multiples
I use this A LOT for lots of things. It's worth the price due to its multi functionality. You really can't go wrong with this product plus it comes it all sorts of amazing shades which makes it really difficult to just get one.
